CHARLES H. COLLINS, OF ALBANY, NEW YORK.

WINDING DEVICE FOR SETTING-FRAMES.

Application filed January 23, 1918.

To all whom it may concern:

Be it known that I, CHARLES H. COLLINS, a citizen of the United States of America, residing at the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in \Vinding Devices for Setting- Frames, of which the following is a specification.

My invention relates to a winding device for setting frames, and the object of my invention is to provide a device for winding yarn onto a spool particularly adapted for use in Axminster setting frames, and means for automatically insuring the winding of a certain predetermined amount on a spool; together with such elements and combinations as are hereinafter more particularly set forth and claimed. I accomplish these objects by means of the mechanism illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation. Fig. 2 is a vertical section. Fig. 3 is a detail view of the means for imparting motion to the spool and the roller, S, and for regulating the same. Fig. 4 is a detail view of the stop mechanism, showing the position of the parts when the gears are locked. Fig. 5 is a detail view of the stop mechanism, showing the position of the parts when the gears are unlocked and the handle of the hand Wheel, T, is operated to start the machine. Fig. 6 is a detail View of the stop mechanism, showing the position of the parts when the gears are unlocked and the handle of the hand wheel, T, is released.

Similar letters refer to similar parts throughout the several views.

I have shown my device connected with an Axminster setting frame in which the threads, A, after passing through the reed, C, are fed between the rollers, B, B, and after emerging from between the rollers pass through the reed, D, to the spool, E, upon which they are wound. The rollers, B, B, the lower of which is preferably iron, and the upper covered With rubber, are driven by the movement of the threads, A, passing between them and with which they are in close contact. On the ends of the rollers, B, B, are the gears, F, F, which mesh with each other like the gears at the end of a clothes wringing machine. The lower roller, B. is mounted on a shaft, G, which also carries a disk, H, provided with a shallow notch, J, with gently sloping sides, in its periphery Specification of Letters Patent.

with which a projection, Z, on the lever, K, is adapted to engage and when in engagement holds the shaft, G, and prevents its rotation. The teeth on the gear, G, engage with the teeth on the gear, P, mounted on the stud, L, which teeth are, say twenty-five in number. The gear, P, having a different number of teeth than gear, F, say twentyfour, is attached to the disk, M, in the periphery of which is a notch, N, into which a projection, is, on the lever, K, may be inserted. As thus arranged, when the machine is started the projection, l, on the lever, K, is just outside of the notch, J, and the projection, k, on the lever, K, is just out of the notch, N, (see Fig. 5). This action is occasioned by drawing the handle, T, which engages with the pin, t, on the hand wheel, T, against the tension of the spring, T because in doing this the hand wheel, T, which is keyed to the shaft, G, moves the disk, H, and the projection, l, rides up the sloping side of the notch, J, emerges therefrom raising the lever, K, lifts the projection, k, out of the notch, N, and thus permits the mo"e ment of the machine. The rotation of the rollers, B, B, will cause the disks, H and M, to revolve a certain number of times before the notches, J and N, will again coincide with the projections, Z and is, on the lever, K. In the meantime the projections, k and Z, will ride on the periphery of the disks, M and H, as shown in Fig. 6, until they again enter their respective notches as shown in Fig. 4. lVhen they do thus coincide these projections will, by enter-in the notches, J, and N, stop the rollers, B, In order to remove the spool the operator may move the handle, T, as above stated, unlocking the disks and permitting the yarn to be progressed and thereby enabling the operator to take the spool out.

It is apparent by arranging the gears, F and P, in proper relation to each other a predetermined number of revolutions of the rollers, B, B, may be provided for before the notches in the disks coincide and the machine will stop. Therefore, by this means I have provided for accurately measuring or determining the quantity of thread wound onto the spool and there can thus be placed upon each spool an equal quantity.

The arrangement of the spool, E, is such that it lies upon and partially between the two rollers, R, R, as shown in Fig. 2. The

roller, S, is mounted above the spool and rests upon the yarn as it is wound onto the spool, causing the yarn to be pressed closely against the spool and to be wound closely and compactly thereon. The roller, S, is mounted in a suitable bracket, 8, suspended from a frame, U, which frame extends across the machine from one end of the bracket to the other and above the same, and is connected with the vertical bar, V, by means of the strip, a, curved near its end at 'u', as shown in Fig. 1. The bar, V, has secured at the lower end thereof, when in operative position, one end of a spiral spring, V, the other end of which is connected by a link, u, to the frame of the machine. In this Way the resiliency of the spring tends to hold the roller, S, in contact with the windings on the spool. The roller, S, is caused to rotate by means of a sprocket chain, 12, passing over the sprocket wheel, 13, on the shaft, 14, carrying the roller, S, also the sprocket wheel, 15, on a stud, 16, and also over the sprocket wheel, 20, and the stud, 21. The gear, 17, and the stud, 21, meshes with the gear, 18. The stud, 16, is the fulcrum of two lazy tong levers, 23 and 24, the lever, 24, being pivoted at 21, to the bar, V, and the lever, 23, being connected with the bracket 8, carrying the shaft, 14. As thus arranged, when the roller. S, is raised by the increased windings on the spool, E, a motion is conveyed to it by the sprocket chain, 12, the universal joint. 26, in the shaft, 19, permitting the bar. Y, to which the stud, 21, and the shaft carrying the gear, 18, is attached, to rise. against the tension of the spring, V. The shaft, 19, is provided with a friction clutch, 22, and universal joints, 26 and 27'. The friction clutch, 22, may, as shown in Fig. 3, be provided with a cam disk, 28, on the end of the shaft, 29, while the frame, 30, carrying the bolts, 31, 31, and springs, 32, arranged on the bolts, are placed at the end of the shaft, 19, and in such position thereon that the bolts will engage the cam disk, 28, as shown in Fig. 3. The springs, 32, on the bolts are compressed when the action of the cam disk is such as to press the bolts into the frame. I preferably make the cam disk as shown in Fig. 3 with a gradual rise until the extreme position of the cam is reached, when there is a sudden break in the contour as at 33. Thus as the shaft, 29, rotates, the friction of the ends of the bolts, 31, 31, against the disk will cause the shaft, 19, to rotate. IVhen, however, the disks, H and M, are locked by the lever, K, and the rollers, B, B, are stopped, there will be a pull on the spool, E, which will be communicated to the shaft, 19, through the gears on the rollers, R, R, which will so affect the shaft, 19, that the bolts will slip on the disk and will not rotate the shaft, 29. The sprocket wheel, 34, is connected by the sprocket chain, 35, with the sprocket wheel, 36, on the shaft 37 which is provided with a clutch, 38, and pulley, 39. \Vhen the jointed rod, 41, falls by the engagement of the lever, K, and projection, K, thereon in the notch, N, and the ointed rod comes in contact with one of the pins, 13, the lever, 41, will be raised and the clutch, 38, moved out of engagement with the pulley, 39, thus stopping the machine subsequent to the stoppage of the tension rollers.

For the purpose of adjusting the rollers, B, B, so as to give the desired amount of tension or pull on the thread, I place on the roller a rod, 60, engaging the bearing bracket, 61, into which it may be screwed, The jam nut, 62, is arranged to hold the rod, 60, in engagement withblock, 100, which block is attached to a cam arm, 101, which is keyed to a shaft, 102, to which shaft is attached the lever, 103. The shaft, 102, passes through a block, 101. As thus arranged the rotary movement of the lever, 103, will cause cam arm, 101, to hold the rod, 60, and therefore the upper roller, B, in the desired position. By providing for increasing the tension on the thread, A, I arrange for causing the thread to be wound very tightly upon the spool, E, whereby a much larger quantity of thread can be placed on the spool than will be if the thread were delivered without this tension or with less tension.

In the manufacture of Axminster carpets and rugs the yarn is dyed in plain colors before it is woven. In order to have the design come as it was intended by the designer, it is necessary to prepare each spool separately and every one differently. In an ordinary rug, 12 feet long and 9 feet wide, the goods will have about seven rows of yarn, or tufts, as they are called by those skilled in the art, that is, seven rows to every inch of the Woven fabric; so if the rug or pattern is 7 2 inches long it will take 504 spools to make said pattern according to the design. These spools are all carried around in the loom in their proper order on an endless chain, and each one is inserted through the warps one in each pattern. If twenty or thirty of these spools should run bare the weaver would have to stop weaving and all the yarn left on the remainlng spools would be Wasted. It is obvious that it is very desirable to have the spools run out as evenly as it is possible to make them, as it makes a very large financial saving for the manufacturer. Under the old system a positive and accurate tension and locking device is not used, which results I accomplish with the aid of my tension roller and other new and novel devices.

lVhat I claim as my invention and desire to secure by Letters Patent'is:
